Abstract: Case 2693 ENGINE BLOCK HEATER WITH EXPANSION YOKE       ABSTRACT OF THE DISCLOSURE           An engine block heater adapted for insertion through an opening in the block wall of an automobile engine has a novel yoke assembly for securing the heater within the opening to the block wall.  The yoke assembly includes a pair of wing members each having one end thereof abutting the inner surface of the heater.  The wing members are hinged to a pressure bar such that each wing member is pivotal about an end portion of the pressure bar in the plane of the bar.  A screw passing through a central opening in the heater is connected to the pressure bar. Upon insertion of the heater in the block the screw is tightened to draw the pressure bar towards the inner surface of the heater, which causes the wing members to pivot about the pressure bar.  This results in those ends of the wing members that contact the inner surface of the heater being displaced toward each other across the inner surface while the other ends of the wing members are moved apart from each other until they overlie and engage peripheral portions of the engine block wall surrounding the opening.

Abstract: ABSTRACT OF THE DISCLOSURE         Panels of plastic film are delivered to a perforated vacuum drum which has a knife edged die mounted on its surface.          Each panel is laid over the die and rotates with the drum into rolling contact with an anvil roll which firmly presses the film panel against the knife edge to cut the panel.  After cutting, the film panel continues to rotate with the drum to a position wherein it registers with a blank having a cut-out opening therein which is covered by the film panel.  The areas of the blank surrounding the cut-out opening are covered with an adhesive material which causes the film panel to remain adhered to the blank.   The vacuum drum continues to rotate and, after bonding of the panel to the blank, the drum releases the vacuum draw on the panel.  The cuts formed in the plastic film panels can be straight lines, lines of perforations, or cut-outs bounding areas which are removed from the panel.

Abstract: ABSTRACT OF THE DISCLOSURE          In a moving coil type stereophonicpickup cartridge, an armature is provided having first, second, and third leg por-tions which extend in three substantially mutually orthogonal directions.  A source of magnetic flux is disposed with only one pole thereof adjacent to the first, second and third leg por-tions of the armature.  The magnetic circuits thus constructed, having an open return path, generate signals by changes in the magnetic flux through coils wound on the second and third leg portions due to the movement of the armature relative to the magnetic source.  Variations in the design of the three leg arma-ture and the magnetic source are disclosed.  Practical embodiments of the invention include disclosure of cartridge replacement fea-tures providing convenient electrical connection between moving coils and remainder of the sound reproduction system.

Abstract: ABSTRACT OF THE DISCLOSURE          An active T-coupler for fiber optic local networks which permits collision detection wherein two input        optical fibers are coupled to photodetectors The two optical fibers are coupled to receive light from light sources. Driving the light sources are gate circuits which function in a manner similar to an OR gate, via driver circuits,            These OR gates receive electrical signals from the host station or an input light fiber detector.  Further, the input detectors provide electrical signals to the driving OR gates          to pass the signal on, i.e. repeat, or drive an OR gate  to transmit the signal to the host station.  Thus the coupler can act as an optical re-peater or transmit originally generated light signals in either the forward or reverse directions.  Further, the host station can monitor the electrical signals from the input detectors to detect the occurrence of a data collision while transmitting and thereby react appropriately.

Abstract: Abstract A monitoring system for detecting earth contact of at least one phase of a polyphase network.  Each of the phases in the network is connected by a capacitive-inductive filter to a neutral node which is connected to earth. In one embodiment of the invention, the current flowing from the neutral node to earth is detected by an induction current transformer which provides a signal responsive to said earth current.  The output signal of the induction current transformer is conducted through at least one low pass filter for suppressing harmonics, and rectified to produce a direct current voltage  signal, the amplitude of which is proportional to the amplitude of the fundamental frequency component of said signal.  A fault indicating signal is produced when the direct voltage signal exceeds a predetermined value.

Abstract: T&B 842 ABSTRACT OF THE DISCLOSURE:          An outer self-sustaining shell is assembled with an interior expandable electrically insulative sleeve in fluid sealed relation with the shell.  A valve is in fluid communication with the sleeve through the shell and is responsive to fluid pressure to permit ex-pansion of the sleeve and retention of the sleeve in expanded state.  Interruption of the fluid sealed relation of the shell and sleeve, as by removing the valve from the assembly, causes collapse of the expanded sleeve onto a cable providing an electrically insulated, watertight and flexible covering.  Methods for cable covering and apparatus for installing the covering are also set forth.

Abstract: METHOD AND APPARATUS FOR WETTING POWDER    ABSTRACT           A high kinetic energy water spraying apparatus wets powdered or granular dry material, particularly hard-to-wet polymers, to provide a lump-free solution of a controlled concentration.          A volumetric feeder drops the dry material through a frustoconical upper portion of the apparatus.  Water is injected tangentially so that the inner surface of the upper portion is completely wetted to prevent buildup of dry material on the surface.         A lower portion of the apparatus comprises a cylindrical column which receives dry material from the upper portion.  The inner surface of the column includes a series of spray nozzles positioned to produce downwardly sloped and radially inwardly oriented jets of liquid which impinge falling dry material with high energy.  The downward slope of the jets creates a downward air flow so that any dust from the dry material is drawn downwardly into the column.

Abstract: ABSTRACT OF THE DISCLOSURE   The invention provides a method of obtaining a purified and concen-trated magnesium chloride-containing brine from a crude brine containing magnesium chloride and also sodium chloride, potassium chloride and magnesium sulphate  The method involves a first step of adding carnallite and sodium chloride to the crude brine and decomposing the carnallite, followed by separat-ing crystals of potassium and sodium chloride.  In a second step magnesium chloride-containing brine is added and the brine mixture evaporated to cause crystals of kieserite and sodium chloride to form, These crystals are removed and in a third step the brine is cooled to cause carnallite and sodium chloride crystals to form.  The carnallite and sodium chloride crystals are separated and added to crude brine in the first step.  Some of the purified and concentrated magnesium chloride-containing brine product is recycled to the evaporation step.

Abstract: ABSTRACT OF THE DISCLOSURE In the manufacturing of a spiral pipe, there is first determined a maximum curvature which should be imparted to a strip of pipe forming material in order that a desired residual moment will be imparted to the finished pipe after the strip bent to the maximum curvature is allowed to spring back from the bent condition, which maximum curvature is determined based on the thick-ness, Young's modulus and yield stress of the strip, the desired curvature of the finished pipe, and the residual moment to be imparted to the finished pipe. By adjusting the position of three rows of forming rolls positioned at the apexes of a triangle, the flat strip is continuously bent into a spiral that has the thus determined maximum curvature.  Then, the spirally formed strip is allowed to spring back toward its unbent shape to the diameter of the finished pipe, being stopped m the expansion due to the springback if it reaches the finished pipe diameter before completing springback or being expanded if it completes springback before it reaches the finished pipe diameter.  Finally, the seam of the formed strip is welded when the strip is at the desired diameter of the finished pipe.
